Need Help! Cant Delete *** Exp frm MC.
Need Help! Cant Delete *** Exp frm MC. –
To start with i installed DMS Exp v1 with the icon fix (d/l from the net eur..) and it worked fine.
Checked the size and found it to be about 500 odd kb so i compressed it, created another image, burnt it off and installed it. This time only taking up 106kb "sweet".
Next project was to correct the media players icon's.
opened up the image for v1.5 extracted the Install, system and media player elf and took a look:
The only file i was interested in was the Install.cnf which looked like this:
_COPY cdrom0:\PS2MEDIA.ELF;1 mc0:\BOOT\DIVX\PS2MEDIA.ELF
_COPY cdrom0:\ogg.ELF;1 mc0:\BOOT\DIVX\ogg.ELF
_COPY cdrom0:\cdvd.IRX;1 mc0:\BOOT\DIVX\cdvd.IRX
From here i changed it to:
_COPY cdrom0:\PS2MEDIA.ELF;1 mc0:/BOOT/DIVX/PS2MEDIA.ELF
_COPY cdrom0:\ogg.ELF;1 mc0:/BOOT/DIVX/ogg.ELF
_COPY cdrom0:\cdvd.IRX;1 mc0:/BOOT/DIVX/cdvd.IRX
_COPY cdrom0:\PS2MEDIA.ICO;1 mc0:/BOOT/DIVX/ps2media.ico
_COPY cdrom0:\ICON.SYS;1 mc0:/BOOT/DIVX/icon.sys
Icon file was created from SJeeps BMP2ICON and sys file created from mcIconSysGen.
Created the image and burnt to cd, installed it and great worked sweet.
Checked MC in browser and no sign of mediaplayer icon : good. so i tried deleting DMS xplorer and to my horror it failed!
Any advice people
That is one of many possible errors with DMS Explorer, due to the faulty design idea of using subdirectories in its main save folder BOOT. The PS2 Browser doesn't allow subdirectories in any save folders, so copying or erasing such saves is risky and may lead to bad results even if it seems to succeed. (Lost memory blocks.) This is one reason why I've stopped using DMS Explorer.
It was useful for getting my first ELFs onto the memory card, but after that it was more hindrance than help... And it's launching abilities are inferior to LaunchELF in any case, which is the launcher I use today. (Can also launch stuff from HDD.)
With that as BOOT.ELF in mc0:/BOOT, together with ExecFTPs.ELF, there's no need for DMS Explorer anymore. You can install and maintain stuff on your MCs via FTP, and avoid any need for subdirectories. That is what I do today and I'd advice you to do the same, or at least something similar, as there are many other tools available that can achieve the same results.
But first you must of course deal with that corrupted card...
The only known cure for MC corruption is to erase all the contents of the card, with the memory card killer app (aka: MCkiller). Hopefully you can copy all game saves from that card before erasing it.

Thanx for that informative response, I guess i'll have to erase the whole card :-(
A few Q's tho' before i start.
1.) Do i install MCkiller on a mem card to erase it i.e mem card 2 to erase mem card 1? If not then how?
2.) Do i need a router for FTP as i dont have 1. I do however have a hub.
3) Can i copy the contents of the MC to a USB pen and then erase and if so do
I have to install the USB application on the MC?
And finally should i ditch DMS Exp for launch elf as u have mentioned its superior to DMS Expl and will that be able to save app in sub directories or is that a no no all together.
try using the delete option in nport first. If you have an xport you can try the delete function from there too.
Im useless arnt i. I dont have that either.
question for you:
What do i invest in? A router or xport? lol.
The normal way to launch MC killer is from a CD-R. It will then erase MC0, but I suggest you have only that card inserted at the time. (That's how I've done it.) It's supposed to be installable to MC as well, but I never tried that myself.
I don't want it in my PS2 except when it must be used. Sooner or later, I might select it by mistake when browsing for a file to launch, and that would be the end of those saves. So I think it's best to keep it on CD, and keep that disk where you know you can't grab it by mistake to put in your PS2.
There are many ways to connect PS2 to PC. The simplest is just a single cross-connecting cable, but then you have no connection to Internet...
A hub is fine too, using normal cables to each of PS2 and PC, and some additional cable to internet, just as you would do it with a router. The difference is that with no router both your machines can be reached from Internet, and there are hostile 'bots' out there that 'sniff' for FTP servers. Since ExecFTPs has NO security, this could be very bad indeed... A router acts as a 'Firewall' protecting both your PC and PS2 from unwanted access by outsiders.
I use another setup myself, having two LANs. One for connecting non-PC stuff (including the PS2) to my main PC through a hub, and another connecting my two PCs to each other and the internet through a router. There are endless possibilities...
As you seem to be thinking, it would indeed be a good idea to prepare another MC beforehand with the stuff you'll need, but I can't advice you about the USB stuff as I don't have any and have never used any with a PS2. (Except Eye-Toy )
Since I myself ditched DMS Explorer to use LaunchELF instead, that is naturally what I advice others with the same problem to do as well. I've never regretted doing it. But saves with more than one folder level in the MC is ALWAYS a nono, as the PS2 browser may then corrupt the MC again, if you accidentally try to copy or delete a folder with subfolders. It happened three times to me before I understood how it works, so I'll never do it again.
If you want normal folder trees like on a PC, then use the HDD instead of MC. And yes, LaunchELF does support programs on HDD. That's how I mostly use it myself, for launching many different programs.
As for the investment, I'd say network security has somewhat higher priority than a gamesave gadget, but the important thing is what you yourself want.

dlanor, dms explorer is OK, there just aren't any safeguards for doing anything stupid (copying into nested directories, etc)
when you use the directory separator fix (/ instead of \), you open up a few dangers, like copying to multiple directories. so don't do that in the future
Im intrigued about using this hub setup...
Is it at all possible for you to explain a few steps (please i knw im asking a bit here) to set a hub up to work with execftp?
I have a Netgear 5 port hub + 1 Upstream??
WinXP and Broadband internet
A simple hub (unlike a router) has no intelligence at all built in. It simply acts as a junction box, connecting a number of ethernet units to each other. All the intelligence of the setup consists of letting each unit know the relevant IP address to use for itself and for any other unit it should communicate with. In your case, there's just a PC and a PS2, so it's very simple.
For connections to units outside of a LAN it's also necessary to know the IP address of one unit on the LAN that will act as 'gateway' for that traffic, and to tell the difference between on-LAN and off-LAN addresses a 'network mask' is needed. That mask defines the bits of the IP addresses that must be identical for all units on this LAN. For example, With a mask of 255.255.255.0 the LAN can contain 256 IP addresses as the 8 lowest bits may vary between units.
So the minimum setup for a unit on the LAN consists of these three parts:
1: IP address of the unit itself
2: Netmask to recognize on-LAN addresses
3: Gateway for transfers off-LAN (Normally your PC)
You can read more on how each homebrew app for networking wants that info set up in the separate docs that come with those apps, or in the various tutorials that exist for PS2 networking.
However, when you connect to Internet you must also follow the rules of your Internet provider, which usually means using the IP address assigned to you by their DHCP server. Using that IP address in communication with the PS2 is a bit awkward, as there is no good way of making it fit into a LAN, unless you have a subnet reserved for you by the provider (very rare).
That problem would be eliminated when using a router, since that allows you to define a LAN independent of the IP defined by your provider. Another way around it is to use a second networking card in your PC, using that for the LAN with the PS2.
You seem to have misunderstood the problem.
There is no problem at all in copying to nested subdirectories with homebrew apps, but there is a problem with the PS2 Browser, which is implemented to ignore the existence of subdirectories. Copying or erasing 'saves' that contain such will lead to problems. That is why no homebrew app (including DMS Explorer) should use such subdirectories on the MC.
DMS Explorer without the separator fix is not capable of installing anything correctly (though the apps work, the PS2 Browser displays lots of garbage) and with the separator fix it installs them to subdirectories. BOTH types of installation are thus unsuitable.
A better method of implementation would have been to create a sepatate 'save' folder for each app (with its own icon file and icon.sys of course). It would have cost a little more MC space per app, but that is the inevitable price of full compatibility.

dlanor, i think you have misunderstood what i've misunderstood
the bad file separator(i think) was put there on purpose. the dms3 boots the file "\BOOT\BOOT.ELF" but it also boots "/BOOT/BOOT.ELF", which sujjests the original authors thought that maybe someone didn't like dms's way to safeguard against noobs. if they didn't do this there would be lots of people with broken mc's ! let me elaborate
the reason the bad separator was invented was to allow users to delete files from the browser, because the ps2 will see each of them as just a file! \BOOT\BOOT.ELF, and \BOOT\DIR\BLAH.ELF are 2 files. with just different file names.
by spec nothing is meant to make dirs within dirs, so if you try to delete files in a nested directory, it just won't work, it's out of spec.
this is why, to make sure it's not out of spec, the dms uses the false dir separator.
and when people use the correct file separators in their install.cnf's, you are actauly able to make *real* subdirs within *real* dirs. which is bad. so when using the dir separator fix, users must be careful not to feed install.cnfs into the explorer with /dir1/dir2/ entrys included
lots of entrys in the browser is better than alot of forum noobs nagging at you regarding broken memory cards. heh
[edit: i know you already know all this but i'm just reclarifying my upper post
